Frank, my man, will you please stop conveying these baseless absolutes; some
of the innocents might believe you know what you are talking about and get
their tits in a wringer.

The Idle Stabilizer Control Valve (ISV) is just that, a CONTROL VALVE.  It is
not a solenoid stop valve that operates as an all-or-nothing devise.  The ISV
functions on the principle of a duty cycle or dwell.  Unless the coil of an
ISV has an open circuit, connecting it to a battery charge will only prove
that the ISV can make a loud clack!!! as its slug slams against the end of
its housing.  As an added benefit of your testing regimen, the ISV can be
ruined from the shock of this self-abuse or because its duty cycle is
exceeded and the coil can't stand all those tender loving amps coursing
through its windings.

In use, the ISV hovers about a point determined by a fluctuating supply
current of 20 mA - 430 mA.  That is why it is supposed to hum rather than
sound like a riveter at work.  So, the next time you are going to whack an
ISV with a battery charger, why don't you first measure its DC resistance in
order to appreciate what you are about to do to it.
